Wilwood Small Ford 2.50-Inch Offset Rear Brake Kit with Red Four-Piston Calipers, 14-Inch GT Rotors and Electric Parking

Plan rear electric parking around the Small Ford 2.50-inch axle interface, red four-piston calipers and slotted 14-inch rotors. Check wheel space. This conversion keeps hydraulic service braking and electric parking in separate calipers selected for the documented mounting arrangement. Bill Wood founded Wilwood Engineering in 1977 in Camarillo, California, where the company is based. Wilwood designs and manufactures disc brake systems, producing brake rotors, calipers, master cylinders, fittings, valves and brake lines for motorsport, street-performance and specialized applications. Individual parts are selected to meet the requirements of the complete braking system.

Fitment & Compatibility

This conversion is selected by the Small Ford housing flange and a measured 2.50-inch axle offset. Compare the housing bolt centers, bearing retainer, axle registration and offset with the Wilwood worksheet before choosing a kit. The 1990 Lincoln Town Car entry in the table below requires individual axle verification; model year alone does not establish compatibility. The electric parking system includes its control unit and harness and is for parking, not an emergency stopping brake. Provide compatible hydraulic lines separately and check the complete wheel envelope against DS-1424.
